Pakistan’s power gridand your electricity bill
Wattlas is two tools. One puts the national grid on a map, so you can build a plant, push demand up somewhere and watch the numbers move. The other reads your household bill and tells you where the money went.

Thirty years of these bills, and opinions about all of them. Press a question and see what you get back.
Ask him something
Sample answers
One kilowatt-hour. An appliance rated at one kilowatt, running for one hour, uses one unit. The UNITS box on your bill is the number everything else is worked out from.
Six things the console answers
Some of it is what already exists. The rest is what happens if you change it.
The grid, on a map
Every plant, every substation, every line. Coloured by what it burns and how much it carries.
Wired up properly
The high-voltage network is a real graph here, 66 kV through 500 kV. That includes the Matiari-to-Lahore HVDC link and everything the national backbone hangs off.
Break something and watch
Put up a solar farm. Shut a thermal plant. Crank demand in one province. The rest of the system reacts.
Forecasts you can argue with
Quantile forecasts with honest uncertainty bands, trained on ten years of measured Pakistani hourly demand and weather.
Where it gets tight
Find the transmission that runs hot, and how much storage it takes to firm up renewables when the reserve margin thins.
What the transition costs
Try a build-out. See what it does to reliability, to congestion, and to the emissions curve.
From raw records to an answer
Pull the records
Generation assets and the transmission network come out of open data and permissioned NTDC files, then get knitted into one national model.
Change something
Drop a new asset onto the grid, or move demand. The engine recomputes the provincial balances.
Read what happened
Before and after, on supply and on balance. Every estimate says what kind of number it is.
Go and break the grid
Open the map. Turn on the layers you want. Run a scenario and follow it from the provinces down to individual districts.
This is planning-grade, not a live feed. It runs on open data, permissioned NTDC records and a set of modelling assumptions. Estimates and forecasts are labelled as such wherever they appear.
